竜 TatSu (the successor to Grako <https://bitbucket.org/neogeny/grako/>) is
a tool that takes grammars in a variation of EBNF
<http://en.wikipedia.org/wiki/Ebnf> as input, and outputs memoizing
<http://en.wikipedia.org/wiki/Memoization> (Packrat
<http://bford.info/packrat/>) PEG
<http://en.wikipedia.org/wiki/Parsing_expression_grammar> parsers in Python

竜 TatSu can compile a grammar stored in a string into a
tatsu.grammars.Grammar object that can be used to parse any given input,
much like the re <https://docs.python.org/3.7/library/re.html> module does
with regular expressions, or it can generate a Python
<http://python.org/> module
that implements the parser.
